Ericsson recommends that the OMT is used, but if no OMT is available, or it is not possible to connect to the RBS,see Section 10.4 Troubleshooting Using the RBS Indicators on page 193. The section is based on the Replacement Unit Map (RU Map) connected to an alarm. The RU Map consists of two different kinds of RUs: • Physical Units The following RUs are mapped to one single physical unit that can be replaced in the field. −IXU −RRU −TIM (only if an IXU with R-state lower than R5A is used) −PSTU −Fan unit • Logical units The following RUs are handled as one unit, but can actually be one or more physical units. −Antenna: The logical path from the RRU to (and including) the antenna −Battery: The battery backup system including batteries −Environment: External conditions (ambient temperature and site power) −GPS receiver: The synch. signal received and distributed by the GPS receiver 176 EN/LZT 720 0027 Uen R8A 2006-06-27 RBS 2308 and RBS 2309 User’s Guide −GPS receiver DXU cable: The logical link between the GPS receiver and the IXU −IDB: The installation database stored in the RBS, not the physical storage −Y link: The logical link between IXU and RRU(s) For supplementary information about RU maps,see: Fault List Micro EN/LZT 720 0466 10.3.1Reading Fault Status This section describes how to read the fault status, using the OMT. If any fault indicator on the RBS is on, then the fault status must be read. Connect the OMT 1. Remove the lid from the OMT port on the IXU. 2. Connect the OMT cable from the PC serial port 1 to the OMT port on the right-hand side of the IXU. If an extended OMT cable is connected to the OMT port, then connect the OMT cable to the end of the extended OMT cable. P010276B L o c a l/R e m o te IX U te m p .
